-* Device tree bindings for Texas Instruments DaVinci timer
-
-This document provides bindings for the 64-bit timer in the DaVinci
-architecture devices. The timer can be configured as a general-purpose 64-bit
-timer, dual general-purpose 32-bit timers. When configured as dual 32-bit
-timers, each half can operate in conjunction (chain mode) or independently
-(unchained mode) of each other.
-
-The timer is a free running up-counter and can generate interrupts when the
-counter reaches preset counter values.
-
-Also see ../watchdog/davinci-wdt.txt for timers that are configurable as
-watchdog timers.
-
-Required properties:
-
-- compatible : should be "ti,da830-timer".
-- reg : specifies base physical address and count of the registers.
-- interrupts : interrupts generated by the timer.
-- interrupt-names: should be "tint12", "tint34", "cmpint0", "cmpint1",
-		   "cmpint2", "cmpint3", "cmpint4", "cmpint5", "cmpint6",
-		   "cmpint7" ("cmpintX" may be omitted if not present in the
-		   hardware).
-- clocks : the clock feeding the timer clock.
-
-Example:
-
-	clocksource: timer@...00 {
-		compatible = "ti,da830-timer";
-		reg = <0x20000 0x1000>;
-		interrupts = <21>, <22>, <74>, <75>, <76>, <77>, <78>, <79>,
-			     <80>, <81>;
-		interrupt-names = "tint12", "tint34", "cmpint0", "cmpint1",
-				  "cmpint2", "cmpint3", "cmpint4", "cmpint5",
-				  "cmpint6", "cmpint7";
-		clocks = <&pll0_auxclk>;
-	};
